PORTABLE LIGHT.

SPECIFICATION forming part of Letters Patent No. 772,401, dated October 18, 1904.

Application filed April 29, 1903.

To @ZZ whom t may concern:

Be it known that I, GEORGE MARTIN BRTLL, a citizen of the United States, and a resident of the city and county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Portable Lights, of which the following is a specification.

The object of my invention is to provide an incandescent electric hand-light to be used in shops and various places of manufacture in small places where it is impossible to use any other than an incandescent lamp.

It is also the object of my invention that the lamp be attached to a wire, so as to be portable, also to provide means whereby the bulb may be protected against theft or undesirable removal.

I have constructed my lamp in a very inexpensive manner and so that the various parts may be readily detachable for assemblage and the removal of the bulb, and means for connecting the bulb with electric wires.

The lamp is provided with a hook, so that it may be hung up.

Another feature of my invention consists in the tube for connecting the electric wires, its means for attachment to the handle, and the means for detaching the wires to the bulb.

The further object and details of my invention will be more fully hereinafter described, and pointed out in the claims.

In the drawings forming part of this specification, in which similar reference characters indicate corresponding parts throughout, Figure 1 is a side elevation, partly in cross-section, showing my improved lamp and holder. Fig. 2 is an inverted plan view taken on the line 2 2 of Fig. 1 looking in the direction of the arrows. Fig. 3 is a cross-sectionon the line 3 3 of Fig. 2. Fig. 4 is a plan of the guard-rim, showing the attaching-lugs. Fig. 5 is a similar View of the seat therefor, and Fig. 6 shows a hook which may be attached to the upper part of the guard.

In the drawings is shown a handle 1, which is preferably made of wood, and attached to the upper end of which is a cast plate 2 for holding the lamp-guard 3. This plate is provided with a threaded neck 4 to receive an interiorly-threaded lamp-socket 5. The guard serai Nn. 1li/4,78% (No modem 8 incases the electric bulb to protect it from breakage and to prevent the bulb from being removed from the lamp.

The handle 1 has a core 7 passing through it longitudinally and immerging into a similar core in the plate 2. There are also a transverse slot 8 and screws 9 to clamp an insulating protecting-tube 10 in the lower part of the handle in order to protect the wires and their .insulators where they are most likely to become rubbed Aand worn. This tube runs upwardly in the handle as far as the shoulder 11, when it is then held by screwing the screws 9, which forces the bifurcated ends ofthe handle together and securely clamps the tubing. The tubing may extend out from the handle a foot or so, as desired, and is flexible.

rlhe top of the handle or frame 2 is preferably cast in one piece and consists of the cylindrical portion 12, adapted to surround the upper part of the handle and lie flush with the shoulder 13, a iat disk 14,with its means for holding the guard-fra me, and the threaded neck 4. The latter is provided with a lampsocket 5 of any desired construction, having an interiorly-threaded cylindrical portion 5a and which is secured over the neck 4.

To provide means for protecting the bulb from breakage while in use and to prevent the bulb from being removed from the socket, I provide a guard 3, which for simplicity of construction and to be of as little obstruction to the light is made of stout wires 15, looped at the top, forming into an inverted-U shape. The wires are soldered at the top where they cross at 16. The Wires pass downward, and

ytheir ends being bent lat right angles lead through a casting 17 and are riveted on the outer side.

As a means of seating the guard on the handleI have provided an interlocking means as follows: From the periphery of the plate 2 extend inwardly seats 18, one of the seats, 19,

being somewhat larger than the rest and provided with a hole 20. On the plate are also provided upturned lingers 21, vhaving the straight portion 22 and the angular lip23. These lingers are preferably arranged between the seats 18 on the plate. The casting 17 is provided with projections 24 on the inner side IOO of the rim to engage with the fingers of the l main plate. The rim 17 is also provided with an extension 25, having a hole 26,which rests upon the similar extension of the main plate, and a lock 27 is passed through the two holes and locks both castings together'. When the guard-frame is attached to the top of the main plate, it is brought down over it, so that the projections 24: are between the lingers 21, the lower rim of the casting 17 resting on the extensions 18 of the main frame. The guard is then revolved on its seat until the extensions 211 pass under the lingers 21 of the main frame and become securely held against the latter. When the guard is revolved until seared, the two projections 19 and 25 overlap. The lock is then inserted in their respective apertures, thus locking the guard to the lower frame and preventing its being removed.

rlhe insulated electric wires 28 pass through the tube 10, then through the upper core 7 of the handle and into the socket 5, where they are connected in the usual way.

rlhe hook 29, as shown in Fig. 6, may be attached to the top of the guard to hang up the lamp when not in use.

Having described my invention, what I claim is- 1. A portable lamp comprising a handle, a plate attached to the handle extending therefrom, lingers on said plate, a bulb, al guard attached to said plate, and having means for engaging with the lingers on said plate.

2. A portable lamp comprising a handle, a plate, extending outwardly from the handle, lingers on said plate having inclined engaging ends, a bulb, a guard therefor seated on said plate, means on the guard for engaging' with the inclined ends of said lingers on the plate, and means for locking the guard against rotation on said plate.

3. A portable lamp comprising a handle, a plate extending outwardly therefrom,`lingers on said plate, a socket and bulb, a guard over said bulb having projections to engage with the fingers on said plate, and hold the guard on said plate.

L1. A portable lamp comprising a handle, a top plate extending outwardly therefrom, peripheral extensions on said plate, lingers on the said plate, a socket and bulb, a guard for said bulb, having' projections to engage with the lingers on said plate, to secure the guard to said plate.

5. A portable lamp having a handle, a plate extending outwardly therefrom, peripheral extensions on said plate, fingers on said plate, a socket and bulb, a guard for said bulb com` posed of wires attached to a rim, said rim having means for engaging the fingers on said plate, a tongue on said rim to overlap one of the peripheral extensions on said plate and means for locking the said tongue and peripheral extension together.

6. A portable lamp comprising a handle', a plate extending outwardly therefrom, peripheral extensions on said plate, asocliet and bulb, a guard therefor, having a lower rim, and means whereby said rim may be seated on said peripheral extensions and by turning said rim the guard becomes fastened to said plate.

7. A lamp comprising a bifurcated handle,a

4 core in said handle, a liexible tube in said core,

means for clamping said bifurcated portion against said tube, a plate on top of said handle, extending outwardly therefrom, peripheral extensions on said plate, fingers on the upper side of said plate, a neel; extending upwardly from said plate, a socket and bulb mounted thereon, electric wires passing through said tube and handle, leading to the said bulb, a guard for the bulb comprising wires passing over the top thereof, and secured at their ends to a rim, means on said rim for engaging the fingers on said plate, a tongue on said rim, and means for locking the tongue to one of said peripheral extensions on said plate.

Signed in the city and county of Philadelphia this 27th day of'April, 1903.
